iting) and variable costs (such as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $ 60,346 , and the variable costs will be $ 10.50 per book. With the other method, the one-time fixed costs will total $ 18,682 , and the variable costs will be $ 21 per book. For how many books produced will the costs from the two methods be the same? books

Equation :

10.50x \: + 60346 = 21x \: + 18682

Move terms,

10.5x + 60346 = 21x \\ \: \: \: \: \: \: \: \: \: \: \: \: - \: 18682 =41664

Move terms again,

41664 = 21x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: - \: 10.5x = 10.5x

Rewrite,

41664 = 10.5x

Divide both sides by 10.5x,

3968 = x

~~

Answer :

If 3,968 books are produced the costs form the two methods will be the same.

Suppose x books are produced by both methods.
Total cost for method 1 = 60346 + 10.5x
Total cost for method 2 = 18682 + 21x

Cost of method 1 = Cost of method 2
60346 + 10.5x = 18682 + 21x
60346 - 18682 = 21x - 10.5x
41664 = 10.5x
x = 41664/10.5
x = 3968

For 3968 books produced the cost by both methods will be the same.

Problem 8
SpyIntel [72]
Answer:

Explanation:

1. x represent the copybook while y represent the pen that is bought.

2. 2x + 3y = 9000 means that in order to buy 2 copybooks and 3 pen you have to pay 9000 LL.

3. Solve for the price of x and y

2x + 3y = 9000 (1)
4x + 2y = 8000 (2)

Multiply (1) by -2:

-2(2x + 3y = 9000)
4x + 2y = 8000
——————————
-4x - 6y = -18000
4x + 2y = 8000
—————————
-4y = -10000
y = -10000/-4
y = 2500

Substitute y value into (2):

4x + 2(2500) = 8000
4x + 5000 = 8000
4x = 3000
x = 3000/4
x = 750

Therefore, 1 copy book = 750LL and 1 pen = 2500 LL
